APPARATUS FOR SINGEING LACES, CLOTH, 80C.

SPECIFICATION forming part of Letters Patent No. 373,857, dated November 29, 1887.

Application filed June 18, 1885. Serial No. 169,040. (No model.)

provement in Apparatus for Singeing Laces,

Cloth, 860., of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Our invention relates to machines for singeing laces, cloth, and other textiles, wherein a flame of gas, preferably hydrogen gas, or of an admixture of hydrogen gas and air, is employed to remove the superfluous fibers from such materials; and it has for its object the production of a simplified and effective gas-delivery apparatus of such construction as to enable the gas to be delivered, when ignited, in a continuous sheet or body of flame, so that as the cloth to be singed is passed through the flame it will be subjected to the action thereof in all its parts to thoroughly rid it of its super= fluous fibers.

The invention consists, primarily, of a gasdelivery pipe having a continuous slit or aperture in the line of the axis of the pipe, and

preferably of a length substantially equal to the width of the cloth to be singed, so as to permit the discharge or escape of gas therefrom in sheet form, when ignited, to act upon and singe the cloth throughout its entire width, the said delivery-pipe being provided with a gas-supply pipe at either or both its ends, and with a clamp or clamps to engage said pipe and prevent widening of the slit therein, combined with a hood and connected exhaust-pipe arranged opposite the continuous slit or aperture in said delivery-pipe, and with cloth-conveying apparatus to pass the cloth to be singed between the gas-delivery pipe and the exhaustplpe.

The invention consists, further, in the combination, with the slitted delivery-pipe, of a clamp or clamps to engage the pipe and prevent widening of the slit or discharge-aperture therein when subjected to the action of the heat from the ignited gas. I

The invention consists of other and minor details, substantially as hereinafter described, and fully pointed out in the claims.

Figure 1 is a longitudinal vertical sect-ion of a machine for singeing textiles,which embodies our invention; Fig. 2, a sectional view on the line as m, Fig. 1, some of the parts being shown in elevation; Fig. 3, a detail'to be referred to showing the slitted delivery-pipe and exhaustpipe in section; Fig. 4, a front elevation of the gas-delivery pipe with its clamps and coverplates and supporting parts; Fig. 5, a detail perspective view of a part of the slitted delivery-pipe, one of its clamps, and a part of the clamp-support; Fig. 6, a similar view of one of the cover-plates with its retainingring and set-screw.

The frame K, the cloth-conveying apparatus consisting of the rolls 2 3 4 5 6 7 8, supported by the frame, the tank B, with its wet roll 12,

are or may be of usual or preferred construction. The rolls 7 and 8 constitute the friction or drawing rolls with the cloth passing around and between them, the shaft of the roll 7 having a belt-pulley, 17, to receive a belt from suitable driving mechanism, whereby the cloth 7 5 may be drawn or conveyed about the rolls 2, 3, 4, 5, and 6, as shown by dotted lines in Fig. 1.

In the present instance we have shown two gasdelivery pipes, e f, one above the other,

and each being connected with the main gassupply pipe E by branch pipes e, which connect with the ends of the gas-delivery pipes,as shown in Fig. 4,whereby gas is supplied to the latter at each end,which insures a better, more 8 5 even, and stronger flow of gas from the said delivery-pipe through the continuous slit or aperture 6 thereof, which is cut through the wall of the pipe in the line of its axis and for the entire length or nearly the entire length of the pipe, as may be desired, the length of the delivery-pipe as well as the length of the aperture or slit 6 therein being preferably governed by the width of the cloth which it is desired to singe in the machine to remove the superfluous fibers therefrom, the slit being preferably made of a length substantially equal to the maximum width of the cloth to .be singed in the machine, so that the flame of gas issuing from the slit shall reach and act I 0 upon every part of the cloth as it is passed through the flame by the cloth-conveying apparatus. The slit 0 in the delivery-pipe being thus made of a length to enable cloth of the maximum width to be singed, clot-l1 of a less width may be singed and the flame of gas confined to a length equal to such lesser width of cloth by the employment of a cover-plate, m, at either or both ends of the gas-delivery pipe to cover such part ofthe delivery exit or slit e as may be desired, each of said plates being adjustably secured to the delivery-pipe by a retainingring, at, and set-screw in", as clearly shown in Figs. -:t and 6. The slit or aperture 0* in the deli\'ery-pi .)e is maintained in its normal condition as against undue ex pansion of the pipe and consequent widening of the slit because of the heat to which the pipe is exposed from the ignited gas by means of clamps 7:, the jaws of which are bolted together, as shown. The clamps 7c are bolted to the cross-bar it of the frame K,and thus serve as supports for the delivery-pipe cf. A hood, f, is arranged above or opposite the exit orifice or slit of each delivery-pipe cf, which connects with the exhaust-pipe F, having an exhaust, G, so as to render the flame strong and steady and also to carry off the products of combustion, the purpose of both hoods so connected with the exhaust-pipe in connection with the two delivery-pipes ef, and the cloth conveying apparatus previously described being to subject both sides or surfaces of the.cloth to the action of the flames of gas.

As shown by the dotted lines, the cloth is carried about the rolls 2 3 and between the lower gas-delivery pipe, 0, and its hoodf to be subjected to the action of the flame of gas issuing from the slit e of the said deliverypipe, thence about the rolls 4 5, and between the upper gas-delivery pipe,f, and its hood to have its other side there subjected to the action of the gas-flame issuing from the slit of said delivery-pipef, thence about the roll 6, over the wet roll I), and about and between the friction or drawing rolls 7 and 8.

\Ve prefer to employ hydrogen gas containing an admixture of atmospheric air or not, as may be desired, as it is productive of far better results than are attained by the use of common carbureted gas. Further, by the employment of the slitted delivery-pipe,with its retaining-claimis to preserve the slit at its normal size, and the cover-plates adjust-ably secured to the said delivery-pipe, we are enabled to produce a strong, compact, and simplified cloth-singeing machine of wide range and capacity and one which effectually and thoroughly removes all superfluous fibers from the material to be singed.

\Ve are aware that it is not new to employ a chamber having at one side an aperture for the discharge or escape of gas or combined gas and air, and provided on its opposite side with a series of openings and a series of pipes communicating with said openings. and we do not claim such as part of our invention; but \Vhat we do claim, and desire to secure by Letters Patent, is

1. A gas-delivery pipe having acontinuous slit or aperture in the line of the axis of the pipe for the discharge or escape of gas in.

sheet form, as set forth, a clamp or clamps to engage the pipe and prevent widening of the slit therein, and a gas-supply pipe or pipes at its ends, as set forth, combined with a hood arranged opposite the continuous slit or aperture in said delivery-pipe, an exhaust-pipe connected with the hood, and clotli-conveying apparatus to convey the cloth to be singed between the gas-delivery pipe and hood, as and for the purpose set forth.

2. The slitted delivery-pipe provided with a cover-plate having a retaining-ring and setscrews, for the purpose set forth.

8. The slitted delivery-pipe combined with a clamp to engage the pipe and prevent widening of the slit therein, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
